Google PageRank™
• Sergey Brin and Lawrence Page (Stanford, 1995)
• Intuition behind PageRank:– Web is a network (graph) connected by links– A link is a "vote" for the destination page– Strength of vote is a fraction of the PageRank
of the page casting the vote
![Page 9: Webs of People, Webs of Data](https://reader036.vdocument.in/reader036/viewer/2022062412/58d0d7f41a28ab47238b5c3b/html5/thumbnails/9.jpg)
PageRank of a page is the
probability of a random
surfer arriving at that page
after many clicks.
(By Markov Theory)

Semantic Web
The Semantic Web is a graph-based knowledge representation of data, spanning the Web, traditional databases, the desktop and mobile devices.

Exabyte Scale Informatics
• 1 Exabyte = 1018 bytes i.e. 1,000,000,000,000,000,000 bytes
• 1 Exabyte is approximately everything ever:• written,• composed,• filmed,• painted• or in any other way 'recorded' by humans.
• Manual classification and retrieval is inadequate; machine learning and data mining are essential.
